The cast iron housing accepts a 1-7\/16 inch bore with a 52100 steel ball bearing insert locked in place by a set screw. Static load capacity is 4,467 pounds and dynamic load capacity is 7,340 pounds, making this unit suitable for moderate-to-heavy radial load applications. Lubrication is required during installation and at regular service intervals. This bearing is installed by millwrights, maintenance technicians, and mechanical contractors on conveyor systems, fans, pumps, and similar rotating equipment.\u003c\/p\u003e\n\u003cp\u003eThis 4-bolt flange unit fits standard industrial mounting surfaces with 4 inch center-to-center bolt hole spacing using 1\/2 inch bolts. The overall length and overall height are each 5-1\/8 inches. Maximum rated speed is 3,500 RPM. Typical applications include HVAC fan assemblies, material handling conveyors, agricultural equipment drives, and light-to-medium industrial machinery where a rigid four-bolt mounting configuration is required for shaft alignment and load management.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-7\/16 inch bore with set screw lock for secure shaft retention\u003c\/li\u003e\n  \u003cli\u003e4,467 lb static load capacity and 7,340 lb dynamic load capacity\u003c\/li\u003e\n  \u003cli\u003eCast iron housing for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003e52100 steel ball bearing insert for reliable radial load performance\u003c\/li\u003e\n  \u003cli\u003e4-bolt mounting pattern with 4 inch center-to-center spacing and 1\/2 inch bolt size\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 3,500 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation 4-bolt flange bearing unit for industrial shafting applications requiring a 1-7\/16 inch bore and a four-bolt rigid mount housing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the driven equipment before removing or installing bearing units, following applicable OSHA lockout\/tagout procedures. Ensure the mounting surface is flat and clean before torquing the four flange bolts evenly. This bearing requires grease lubrication at initial installation and per the equipment manufacturer's maintenance schedule — do not operate dry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VF4S 300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Insert Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Type\u003c\/strong\u003e: 4-Bolt Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore (Inside Diameter)\u003c\/strong\u003e: 1-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 5-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 1-19\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Height\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2-1\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Center-to-Center\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase-to-Center Distance\u003c\/strong\u003e: 1.188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStatic Load Capacity\u003c\/strong\u003e: 4,467 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDynamic Load Capacity\u003c\/strong\u003e: 7,340 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Type\u003c\/strong\u003e: Set Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: 52100 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLubrication\u003c\/strong\u003e: Required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171500\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BROWNING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 767494\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51543005757746,"sku":"767494","price":280.25,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bf43186ef266874d7e773f94df5574d.jpg?v=1785913517","url":"https:\/\/voomisupply.com\/products\/browning-767494-4-bolt-flange-bearing-1-7-16-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
